I have just taken over a site with R600/R500's running unleashed. The site uses a proxy and some severe firewalls that prevent direct access to the internet. The APs are running 126.96.36.199.608 and the administer>upgrade only gives one button to upgrade which fails. The Dashboard seems to think it has internet access but this is not the case. How do I get the option to manually update the APs?
From a workstation on your Unleashed WLAN, so you you can get to the Admin GUI, try a Manual upgradeand point to your Master AP model image. Disclaimer: I can't remember if original 200.0 Unleashed has the Manual upgrade option... =:^( If worse comes to worst, you might need to document your WLAN configurations, etc and upgrade an AP bya direct connect to your PC and factory default the AP to 192.168.0.1, onto the current Unleashed release, and create the network again, then add the remaining R500/R600s (that will auto-upgrade when recognized).
